What LLMs are you using? Just simply telling Sol 6.1, Opus 5.5, Fable or Astra to performance test something will get you a solid improvement in poorly optimized code.
Giving it a specific plan will get you a solid test harness.
And setting up an autoresearch system and running it overnight will get you expert level optimizations if you set the metric up right.
